With the social development and improvement of people's living standards, the use of various steel is also more and more in many ways. Stainless steel pipe and carbon steel pipe play an active role in building decoration and machinery and equipment industries.

However, it is worth noting that the material of the carbon steel pipe is different from that of stainless steel pipe, so they can’t be stacked together. At room temperature, when the carbon steel pipe is in contact with the stainless steel pipe, it will not be carburized immediately. The speckled rust on the stainless steel tube will only occur after a certain period. In a humid environment, it is easy to produce a chemical reaction if the carbon steel pipe and the stainless steel pipe are stacked together, thus damaging the protective coating of the stainless steel pipe, resulting in the rust of the stainless steel pipe.

In addition, if different types of steel are stacked together in contact with each other, electric potential difference will be generated then resulting in galvanic corrosion. Especially when there is water, electrochemical corrosion rate between stainless steel pipe and carbon steel pipe will be accelerated. Just like the battery principle, chemistry in a chemical cell can be directly converted to electricity because of the oxidation reduction reaction inside the battery. In order to prevent electrochemical corrosion and carburizing of the stainless steel pipe, it’s better to store carbon steel pipe and stainless steel pipe separately.

Carbon steel pipe is developing with the development of the world. The problem of rust has been completely solved with the development of carbon steel pipe. The biggest advantage of carbon steel is that the problem of pipeline rust has been solved. The antioxidant performance of general steel pipe is poor, so pipeline will easily contact with oxygen in the air if application environment can’t be strictly controlled in the process of use. The iron in the steel tube is an active metal component. After contacting with oxygen, it is very easy to have an oxidation reaction.
